[mcj]WordPress增加超过一定时间旧文章提示-马春杰杰

方法1：

效果：

打开functions.php，加入：

//添加老文章提示信息 
function old_content_message($content) {
$modified = get_the_modified_time('U');
$current = current_time('timestamp');
$diffTime = ($current - $modified) / (60 * 60 * 24);
global $wp;
$current_url = home_url(add_query_arg(array(),$wp->request));
if ($diffTime > 365 and !strstr($current_url, "feel")   ) {
$content =  $content.'<div class="warn">本文最后更新于'.get_the_modified_time('Y年n月j日').
'，已超过 1 年没有更新，如果文章内容或图片资源失效，请留言反馈，我们会及时处理，谢谢！</div>';
}
return $content;
}
add_filter('the_content', 'old_content_message');

//添加老文章提示信息

function old_content_message($content) {

$modified = get_the_modified_time('U');

$current = current_time('timestamp');

$diffTime = ($current - $modified) / (60 * 60 * 24);

global $wp;

$current_url = home_url(add_query_arg(array(),$wp->request));

if ($diffTime > 365 and !strstr($current_url, "feel") ) {

$content = $content.'<div class="warn">本文最后更新于'.get_the_modified_time('Y年n月j日').

'，已超过 1 年没有更新，如果文章内容或图片资源失效，请留言反馈，我们会及时处理，谢谢！</div>';

}

return $content;

}

add_filter('the_content', 'old_content_message');

CSS效果：

.old-message{padding:10px;color: #DB7C22;font-size: 14px;background: #FFFCEF;border: solid 1px #FFBB76;border-radius: 2px;box-shadow: 0 0 3px #ddd;}

1	.old-message{padding:10px;color: #DB7C22;font-size: 14px;background: #FFFCEF;border: solid 1px #FFBB76;border-radius: 2px;box-shadow: 0 0 3px #ddd;}

方法2(推荐)：

functions.php：

//添加老文章提示信息 
function old_content_message($content) {
$modified = get_the_modified_time('U');
$current = current_time('timestamp');
$diffTime = ($current - $modified) / (60 * 60 * 24);
global $wp;
$current_url = home_url(add_query_arg(array(),$wp->request));
if ($diffTime > 365 and !strstr($current_url, "feel")   ) {
$content =  $content.'<div class="warn">本文最后更新于'.get_the_modified_time('Y年n月j日').
'，已超过 1 年没有更新，如果文章内容或图片资源失效，请留言反馈，我们会及时处理，谢谢！</div>';
}
return $content;
}
add_filter('the_content', 'old_content_message');

//添加老文章提示信息

function old_content_message($content) {

$modified = get_the_modified_time('U');

$current = current_time('timestamp');

$diffTime = ($current - $modified) / (60 * 60 * 24);

global $wp;

$current_url = home_url(add_query_arg(array(),$wp->request));

if ($diffTime > 365 and !strstr($current_url, "feel") ) {

$content = $content.'<div class="warn">本文最后更新于'.get_the_modified_time('Y年n月j日').

'，已超过 1 年没有更新，如果文章内容或图片资源失效，请留言反馈，我们会及时处理，谢谢！</div>';

}

return $content;

}

add_filter('the_content', 'old_content_message');

如果想出现在文章开头，则改为：

//添加老文章提示信息 
function old_content_message($content) {
$modified = get_the_modified_time('U');
$current = current_time('timestamp');
$diffTime = ($current - $modified) / (60 * 60 * 24);
global $wp;
$current_url = home_url(add_query_arg(array(),$wp->request));
if ($diffTime > 365 and !strstr($current_url, "feel")   ) {
$content = '<div class="warn">本文最后更新于'.get_the_modified_time('Y年n月j日').
'，已超过 1 年没有更新，如果文章内容或图片资源失效，请留言反馈，我们会及时处理，谢谢！</div>'.$content;
}
return $content;
}
add_filter('the_content', 'old_content_message');

//添加老文章提示信息

function old_content_message($content) {

$modified = get_the_modified_time('U');

$current = current_time('timestamp');

$diffTime = ($current - $modified) / (60 * 60 * 24);

global $wp;

$current_url = home_url(add_query_arg(array(),$wp->request));

if ($diffTime > 365 and !strstr($current_url, "feel") ) {

$content = '<div class="warn">本文最后更新于'.get_the_modified_time('Y年n月j日').

'，已超过 1 年没有更新，如果文章内容或图片资源失效，请留言反馈，我们会及时处理，谢谢！</div>'.$content;

}

return $content;

}

add_filter('the_content', 'old_content_message');
